JOSEPH YONKESE, F BROOKLYN, NEW YORK APPARATUS FOR GENERATING MOTIVEFLUIDS Application filed January 22 1927. "Serial No. 162,785.

My invention relates generally to apparatus for generating motive fluidsand more particularly to; an apparatus which'in one of its adaptationsis capable of being associl 'ated with a prime mover such as an internalcombustion englne in such manner that the heat contained in gasesexhausted by the engine when in operation, can be utilized to generate amotive'fluid such as for instance,

steam, so that the heat from the exhaust gaseswhich is ordinarilydischarged into the at-' mosphere and wasted, is converted into amotivefluid for performing useful work.

' to a maximum.

apparatus from an independent It is a further purpose of my invention toprovide an apparatus of the above described character having means bywhich the power of the motive fluid as generated can be employed to aidin driving the prime mover with .which the apparatus is associated, thusincreasing the efliciency of the prime mover It is another purpose of myinvention to provide an apparatus for generating a motive'fluid which iscapable of use in generating the fluid from the heat of a flameemanating from a suitableburner, so that should the-engine with whichthe apparatus is associated, fail, the motive fluid can be generated bythe source of heat. I

I will describe only one form of apparatus for generating motive fluidsembodying my invention and will then point out the novel features inclaims.

. In the accompanying drawings, i

Fig. 1 is a view showing in vertical longitudinal section one form ofapparatus for generating motive fluids, embodying my invention,associated with an internal combustion engine of the well known V'typeparticularly adapted for airplane use;

Fig. 2 is a sectional view taken on the line 2--2 of Fig. 1 and lookingin the direction of the arrows; and I Fig. 3 is a view illustrating theapparatus in side elevation and the manner in which engine when themotive fluid it is associated with an internal combustion enerated bythe apparatus is to-be employe as an aid in driving'theengine IReferring specifically to the drawings and particularlyto Figs. 1 and 2,my invention in its present embodiment is shown associated with aninternal combustion engine E of the airplane V type having two banks orrows of cylinders C in angular relation, although it is to. beunderstood that my invention can be applied to different type engines.Myapparatus in'the particular embodiment illustrated is designed for thegeneration of steam as the motivefiuid, and to this end I provide aboiler, designated generally at B and comprising a shell 10 ofcylindrical form having. closed ends 11 and 12, the boiler beingsupported in any suitable manner to occupy a horizontal positionlongitudinally of the engine E and between the two'banks of'cylinders C.y l

' The boiler is divided interiorly by a horizontal longitudinallyextending partition 13 of arched crossed-section, and a verical'partition 14 adjacent to and spaced from one end Wall 12 of the boiler,co-operating to provide a water space 15 and a firebox 16 below thewater space communicating at one end with a transverse passage 17 whichlatter in turn communicates with one of the open ends of a plurality oftubes 18 spanning the water space 15 and secured at their ends insuitable openings formed in the vertical partition 14 and the remote endwall 11 of the boiler. The other of the openends of the tubes 18communicates with a manifold 19 terminating ina stack 20 provided with avalve 21 manually operable in any suitable manner to control the outletfrom 'the stack. It will be clear that heat fromthe firebox 16 will befree to discharge from the latter into the passage 17 and thence throughthe tubes 18 to effect by conduction, the heating and conversion intosteam of water contained in the waterspace 15, after which any heat andthe products of combustion remaining from the fuel used will dischar einto the manifold 19 and thence into-51c stack 20 to the atmosphere. Thesteam generated int he boiler is free to enter a steam dome 22 fromwhich leads a pipe 23 for conveying the steam to the desired point ofuse.

To provide the necessary heat to generate the exhaust gases resultingfrom the operation of the engine E is utilized, and to this end, thecylinders C of the engine, instead of exhausting into a common manifoldas is the common practice, are provided with individual exhaust pipes 24which project throu h the side walls of the boiler at a pointimmediately above the partition 13 so as to be disposed in the waterspace 15 and extend transversely of the boiler in side by side relation.The free ends of the pipes 24 are.

downturned as at 25 and project through the partition 13 so as todischarge the exhaust gases directly into the firebox 16 at intervalsalong its length. It will be clear that due to the presence of the pi es24 within the water space 15, a portion 0 the heat of exhaust gasestraversing the pipes will be conducted to the water in the Water spaceso as to initially heat the water, while the remaining heat in thegaseswill accumulate in and dis charge from the firebox 16 through thetubes 18 to further raise the temperature of the water, thus insuringthat practically all the heat units available 111 the exhaust gases willbe utilized before the gases are finally discharged from the stack 20. a

To aid in the conversion of the water in the boiler into steam, waterfrom the cooling system of the. engine, which is in a heated state as aresult of the operation of the engine, can-be pumped from the latterinto the boiler, and to this end I provide a conventional form of pump26 supported on the engine betweenthe banks of cylinders C andhaving twoinlets connected by pipes 27. to the water jackets 28 of the two rows ofcylinders, while thedischarge side of the pump is connected to the waterspace 15 in the boiler by a pipe 29. The pump is adapted to be drivenfrom the crankshaft 30 of the engine Eby a sprocket and chain connection31, and is'capable of being thrown into or out of operation at will, bymeans of a conventional jaw clutch 32 manually operable by means of arod 33 connected to a yoke 34 pivotally mounted at 35 and engaging theclutch collar 36 of the clutch 32. The supply of water to the jackets ofthe engine can be replenished from a suitable source (not shown) througha. pipe 29 controlled by a valve 29, and from which pipe lead'branches29 to the jackets of the respective-cylinders.

Should the operation of the engine E fail, steam can be generated in theboiler independently of the engine, by the provision of a conventionalform of burner 37 mounted on the end wall 11 of'the boiler and havingnozzles 38 and 39 projecting into the firebox 16 and adaptedrespectively for connection to sources of fuel supply and air supplyunder pressure. It will be clear that with the burner 37 in operation,the flame emanating from the nozzle thereof will traverse the firebox 16and will travel in the same path through the boiler as exhaust gasesfrom the engine discharged into the firebox from the exhaust pipes 24 sothat heating of the water and the conversion thereof into steam will beeffected.

In the event that it is desired to employ the power from the steamgenerated in the boiler, to aid in driving the engine E and thusincrease its efficiency to a maximum, the pipe 23 leading from the steamdome 22 is connected to the intake side of a conventional form ofturbine T, the rotor 40 of which is fixed to the crankshaft 30-of theengine While the stator 41 thereof is secured by bolts 42 to one end ofthe engine crankcase 43, all of which is clearly shown in'Fig. 3. Thesteam generated in the boiler from the heat of the gases exhausted fromthe engine when in operation can thus'be directly used to drive theturbine T and as a result materially aid in driving the engine. Thesteam after being used by the turbine is free to discharge therefromthrough a pipe 44. The supply of water to the boiler can be replenishedfrom a suitable source (not shown) through a pipe 44 communicating withthe water space of the boiler and provided with a valve 45.
